ATENT EBENEZER HOSKINS, OF BIRMINGHAM, COUNTY OF \VARWVIOK, ENGLAND.

SPECIFICATION forming part of Letters Patent No. 308,260, dated November 18, 1884.

Application filed December 5, 1883. (No model.)

To all whom it may concern.-

Be it known that I, EBENEZER HosKINs, a subject of the Queen of Great Britain,'residing at Birmingham, in the county of Warend bar, and a length of tube or solid iron of.

any required shape to form the under connecting or strengthening part of the bar. I then place them "in iron molds and pour molten metal into such molds, so as to connect the said bars or rods firmly together in two or more places, and at the same time forming one or more dovetails in or upon each block. I then connect the two ends of the one bar.

with the two ends of the other bar by means of longitudinal bars of iron, either tubular or otherwise, having dovetails cast or fixed at each end of them, thus forming an oblong square frame of required size. The metallicspring mattress is then attached to the frame, and the whole is ready to fix, by means of dovetails, to the head and foot ends of metallic and other bedsteads, ships berths, or invalid furniture;

WVhen the frames are required for wide bedsteads, I use three or more longitudinal bars connected to the frames by dovetails, as before described, to give greater rigidity to the frame.

In the drawings, Figure 1, Sheet 1, is a perspective View of a head end of a metallic bedstead with the dovetails upon it to which the frame is to be connected. Fig. 2 is a perspective View ofthe end bars. Fig. 3 1s a perspective View of the frame with a spring I mattress attached thereto; and Fig. 4, Sheet 2, is a view of the frame as attached to a metallic head and foot end of a bedstead, showing three longitudinal connecting-rods, but omitting the spring-mattress, in order to show more clearly the new parts.

Referring to the drawings by letter, A is the dovetailed block upon the head and foot ends of the bedstead, to which the frame is attached when completed, said block being formed with the dovetailed lug a.

B is the prepared length of angle or other iron, shown in these drawings as angle-iron.

O is the length of tube or solid iron to form the under connecting or strengthening partof the bar. I

D is the molded block, with the dovetails in or upon each of them, the block being formed on one side with dovetailed recesses b, to engage with lugs a, and 011 the opposite side with dovetailed lugs c.

E E are the longitudinal bars, formed with dovetails to engage with the dovetails of the inner face of blocks D and form a close joint, as shown in Figs. 3 and 4.

F is a central block, formed with a dovetailed lug, d,- and G a central longitudinal bar, which will be formed with a dovetail recess to engage with the dovetail lug (I, such as I use when the frames are required for wide bedsteads.

What I claim is- 1. The combination, in a bedstead, of the head and foot pieces having the attached doveing dovetail ends, and the transverse end bars formed with dovetails on opposite faces to engage With the dovetails of the longitudinal bars and head and foot pieces, substantially as and for the purpose set forth.

2. In a bedstead, the combination of the head and foot pieces having attached dovetail blocks A, the longitudinal bars E E, having dovetail ends, and the transverse end pieces composed of angle-plates having end blocks dovetailed to engage with the dovetails of the and the rod 0, connecting with said end blocks, substantially as and for the purpose set forth.
